摘要： The present invention relates in summary to a medical handle for pneumatically or hydraulically operated medical instruments or motor units, with a preferably female coupling part for the mechanical and pneumatic/hydraulic coupling of a corresponding, preferably male coupling part, and a manually activatable valve mechanism for selectively applying pressure to a coupled medical instrument or to the motor unit thereof, which is provided with a safety mechanism for preventing pressure being applied in the case of an uncoupled medical instrument or motor unit thereof. According to the invention, provision is made that the coupling part provided on the handle interacts with the valve mechanism in such a way that the latter is automatically opened during or by the mechanical coupling procedure and/or is enabled for manual opening, whereas the valve mechanism is closed and/or the enablement is cancelled in the uncoupled state.

摘要： A coupling for a surgical rotary drive tool holder comprising a tool which is mounted in the tool holder and rotationally driven thereby and a bushing type rotationally driven receiving element in the tool holder, wherein a shank of the tool can be inserted into the receiving element and rotationally engages therewith in a positive fit, also comprising at least one locking body which can be inserted radially into the inner area of the receiving element, whereby said locking body engages with a shoulder element of the shank when it is inserted in a locking position and secures the latter against axial displacement and said locking body exits from the shoulder element when it is in a radially extracted position, thereby enabling the shank to be displaced axially in the receiving element. The aim of the invention is to simplify use of the tool. In order to achieve positive-fit rotational engagement in the bushing-type receiving element, a carrier - which rotates with the bushing and which is axially displaceable in relation thereto- is provided with at least one bearing surface on the side facing the tool; the carrier can be displaced into an extracted position due to the effect of a spring, wherein the locking body or locking bodies lie adjacent thereto and are thus maintained in a release position; the carrier can be displaced into an inserted position counter to the effect of the spring by means of the shank of the tool adjacent thereto, wherein the locking body or locking bodies can enter into a locking position and the can secure the shank of the tool against axial displacement; the shank of the tool, in an inserted position, can cause the carrier to be inserted counter to a position in which it is secured against axial displacement and counter to the effect of the spring into the receiving element by means of the locking body or locking bodies such that the bearing surfaces thereof are disposed adjacent to bearing surfaces of the tool resulting in rotational engagement.
